Coryza is an icy world along an intergalactic trade route.
The population centres in Coryza mostly serve as supply and rest stops for traders and travellers making the long trek along the route. As such, traffic is often crowded there. Despite it appearing to be an insignificant backwater, rumours seem to indicate that Coryza has multiple assets in place by various galactic governments and organisations wishing for the utmost secrecy in their activities.
Recently, the arrival of the Blackwatch frigate transporting Mazkertis seems to support that theory, especially as the crew of the frigate were ordered to transport the prisoner to a facility on the surface of the planet.
